    What to do if my DUROMAX Engine will not start?

      If your DUROMAX Engine won't start, several issues could be the cause. First, ensure the engine switch and fuel valve are set to “ON”. Check if the choke is closed. Make sure that the engine has enough fuel, and that the fuel isn't old or contaminated (if so, change it). Inspect the spark plug—clean it if it’s dirty, and replace it if it’s broken. Also, verify the engine is on a level surface and that the oil level is sufficient; add or change the oil if needed.
